' Specification ofLetters Patent.

Patented May 9', 1911.

Application filed August 5, 1909. Serial No. 511,268.

To all whom it may concern:

'Be it known that I, ROBERT E. L. J ANNEY, a citizen of the United States, residing at Chicago, in the countyof Cook and State of Illinois, have invented certain new and use.- ful Im rovernents in Car-Couplers, of which the fol owing is a specification.

Myinvention relates to that class ofcouplers of theJanney type which employ a pivoted knuckle, a lock therefor, and a lifter v for operating the lock.

- Specifically described, my invention comprises a coupler-head, aknuckle ,pivoted therein, a-.vert ically movable lock block, a lifterand knuckle-opener for lifting said creeping and lock-setting means applied to the lock block.

head on line 66. of Fig. 5. Fig.7 is a perspective sectional view through the head and shank, showing the lock in the locking position; and Fig. 8 is a' similar view showing the lock on the lock set.

In the drawings, 10 represents the couplerh'ead, 11 the knuckle, and 12 the knucklepin. The lifter 13 is of the vertically movable type and in service is provided with a chain 14 and operating arm 15. The lifter 13 is also provided with a lock-carrying ledge 13, and a downwardly and forwardly extending foot 13*,

cam 13. The-knuckle 11 has a locking-face 11*, a cut-away portion 11 and an enlarge merit 11 provided for a-purpose hereinafter described. The under surface 11 of the knuckle-tail is inclined to form a cam surface which is acted upon by the cam surface 13 of the lifter and opener to assist in opening the knuckle. i

' The lock'is provided with means both for anti-creeping and lock-setting, and as this lock in normal'locked section of the coupler.

the forward face of which is provided with a knuckle opening ,"forms the gist of my invention I will now describe the same in detail.

As will be seen by reference to Figs. 4,

STEEL FOUN- construction of the lock, providing the locksetting means. form, its lower edge 16.? being formed diagonal to the horizontal axis of the lock for a double purpose, as will be hereinafter described. and adapted to coiiperatc with the vertical rib 10 of the coupler-head, I provide a slot 16 of peculiar formation, as shown in Fig.

1. This slot is contracted from its'upper portion to a point near the middle thereof, then is flared from thence to the lower edge of the look. A further cut away portion 16 is provided at the back of the lock. In nornial locked position, as shown in Figs. 1, 4,

Upon one side of the lock 16,

The lock 16 is ofpolygonal 5 and 7, the lock 16 is carried by the diagonal ledge 10 of the coupler head, and, as will be seen in Fig. 7 is slightly inclined or tilted backward, the upper rear corner 16 of which rests beneath the ledge 10 of the coupler-head.

' Upon a lifting movement by the lifter 13, the ledge 13 will raise the rear end of the look first, thus freeing it from the ledge 10. If the lifting movementis continued until the lock is raised to the point shown in the full line position of Fig. 4 andin Fig. 8 the lower front portionof the slot 16 will register with the notch 10 in the rib 10, the cut-away portion 16 of the block allowing the block to-tilt forward in order to occupy the lock-set notch. As will be seen, the knuckle is then free to be swung open and as the lifter is released will drop to normal unexposed position, as shown in Fig. 1. As the knuckle is swung open by the separation'of the cars, the, forward endof the lock is raised by the upward incline on the upper surface of the knuckle-tail, thus releasing it from the' lookset ledge 10, while the rear of the lock being unsupported drops thus placing the lock in an inclined position and carrying the engag ing surface 16 of the lock out of line with the shoulder of the notch 10 The lock is held in this position during the return moveready to the rear ment of the knuckle. When the knuckle is completely closed the lock will fall by gravity to the original position of Fig. 1.

If it is desired to throw the knuckle open the lifting movement is continued .until the knuckle-opening cam 13 of the lifter contacts the cam surface ll 'of the knuckle tail, the cam action forcing the knuckle open,

the lock meanwhile being carried b of the .knuckle. As soon opener is released it its normal position, while carried on the as the lifter and will fall by gravity to the lock being meantail of the knuckle and to drop to locked position upon the return of the knuckle to closed position.

I claim: 1.- In a coupler of the coupler head and a pivoted class described, a knuckle, said head being provided with a notched vertical rib infcombination with a lock adapted to-be 7 said rib, a lifter and opener for. and opening said knuckle,

uided upon ifting said lock said lock being adapted to be supported by the notch in said rib when raised to free the knuckle.

2. In a coupler of the by the lifter class described a coupler-head and pivoted knuckle, said head having a vertical gu1de-rib provided with a lock-set notch and an slide upon said rib,

in the rib when raised to and a lifter adapted to engage the anti-creeping ledge of said rib, a lock mounted to and to seat in the notch lock-set position,

lock to free it from the anti-creeping ledge, and by further movement to raise Copies of this patent may be obtained for the lock to release the taih the knuckle, and finally to tilt the look into engagement with the lock-set.

3. In a coupler of the class described, a v

coupler head and a pivoted knuckle, said rectly associated with said lock and said rib,

and. a combined lifter and opener for lifting said lock and opening said knuckle, substantially as described.

oted knuckle, an anti-creeping ledge, a lock adapted to slide and rock upon said rib and to seat in the notch in said rib when raised to lock-set position, and a combined lifter and opener said knuckle, substantially as described.
